The energy from the heat of the fire makes one of the electrons in potassium jump up to a higher energy level. When it drops back down, the energy difference between the higher level and the one it emits the energy in the form of a photon. Since the energy of each level is fixed, only photons with certain energies (and hence certain colors) can be emitted. For potassium, one of those permitted energies happens to correspond to a photon of a particular shade of violet. The energy levels (and therefore the differences between energy levels) are different for every element. For sodium, there are two permitted energies close together in the orange-yellow part of the spectrum, so sodium turns fire orangeish-yellow; rubidium has a strong line in the red, and caesium has two bright lines in the blue (the names rubidium and caesium come from the Latin words for deep red and sky blue respectively).

What chemical is burning when you see a violet purple flame?

When you see a violet-purple flame, it often indicates the presence of potassium compounds, such as potassium chloride or potassium nitrate. The specific element responsible for the color is potassium.


What color flame test does potassium chloride?

When flame tested, Sodium ions range from a yellow to a bright orange flame and Potassium ions give a lilac or light purple flame. Neither the Sulphate nor the Chloride ions should have emission spectra in the visible range.


What color it emitted by potassium?

In a flame test, the color released by potassium is lilac, which is a light purple. K is the symbol for the chemical element potassium, and its atomic number is 19.


What color does potassium give off?

Potassium ions typically emit a lilac or light purple color when excited, such as in a flame test. This distinctive color is used to identify the presence of potassium in chemical compounds.

A test that can be used to determine whether a solution has potassium sulfate?

To determine if a solution contains potassium sulfate, you can perform a flame test. When a sample of the solution is heated in a flame, the potassium ions will emit a lilac flame color, which is characteristic of potassium compounds. This can help confirm the presence of potassium sulfate in the solution.

What color flame test does the iodide solution give in flame test?

It is not the anions (e.g. iodide) that are responsible for the flame test color, rather the cations such as sodium ion, potassium ion and calcium ion give you different colors.
